There are 5 open security issues in bookworm.
3 issues left for the package maintainer to handle:
- CVE-2025-43903:
(needs triaging)
NSSCryptoSignBackend.cc in Poppler before 25.04.0 does not verify the adbe.pkcs7.sha1 signatures on documents, resulting in potential signature forgeries.
- CVE-2025-50420:
(needs triaging)
An issue in the pdfseparate utility of freedesktop poppler v25.04.0 allows attackers to cause an infinite recursion via supplying a crafted PDF file. This can lead to a Denial of Service (DoS).
- CVE-2025-52886:
(needs triaging)
Poppler is a PDF rendering library. Versions prior to 25.06.0 use `std::atomic_int` for reference counting. Because `std::atomic_int` is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue.
You can find information about how to handle these issues in the security team's documentation.
2 ignored issues:
- CVE-2019-9543:
An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readGenericBitmap() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfseparate binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JArithmeticDecoder::decodeBit.
- CVE-2019-9545:
An issue was discovered in Poppler 0.74.0. A recursive function call, in JBIG2Stream::readTextRegion() located in JBIG2Stream.cc, can be triggered by sending a crafted pdf file to (for example) the pdfimages binary. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact. This is related to JBIG2Bitmap::clearToZero.
